ZoneAlarm Antivirus never does a full scan. It only does a small fraction of the total files on my computer. I use an online scanner to do a full scan. Some antivirus/antispyware solutions give you the option of choosing between a full scan of the computer and what may be called an intelli-scan or smart scan - a scan of critical areas where's there's most likely to be viruses or spyware. I get the impression that ZoneAlarm Antivirus does a "smart scan" only. Am I right?
